Abstract: 350,031. Electromagnetic relays. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and PARRY, R. D., Pen Bryn, Northway, Neasden, Middlesex. Feb. 11, 1930, No. 4606. [Class 38 (v).] Electromagnetic switches; mercury switches.-An electric relay has an operating coil 4 with a magnetic core 2 and yoke-piece 1, a chamber 6 containing mercury 7 being mounted between the end of the core and the yoke and an armature being mounted within the mercury chamber. The lower portion of the armature is surrounded by insulating material 10 so that normally there is no contact between it and the mercury a projection G of the armature being surrounded by an adjustable spring 11 to maintain it out of contact. On energization of the electromagnet the armature is drawn down towards the polepiece which is tapered at its tip to concentrate the magnetic field adjacent to the armature. The displacement of the mercury caused by the downward movement of the armature causes it to rise above the insulating portion 10 and to contact with a conducting ring 8, so completing the controlled circuit. By adjustment of the tension of the spring 11, the value of the current at which this takes place may be varied.

Title: Hydraulic power control device
IPC: B60T13/24
Filed: 1966-02-02
Abstract: 1,105,351. Brake cylinders. SOC. ANON. D.B.A. 2 Feb., 1966 [5 Feb., 1965; 31 Aug., 1965], No. 4608/66. Heading F2F. An hydraulic control for the master-cylinder 12 of a brake system has a servo-motor 10 in which the movements of its piston 44 are effected by pressure in a chamber 70 which is controlled by a servo-valve spool 58 disposed in a chamber 42 between an opening 52 to an accumulator 54 and one 56 to a reservoir (not shown), the displacements of the spool 58 being actuated by a lever 74 pivoted on the casting 14 at 78 and operating on the piston 44 and the spool 58 through a feeler member 76 which is tiltable about an axis 86 carried on the lever 74 so as to move with it when it is tilted by movement of a rod 84 of given cross-sectional area where it extends into the control chamber and is adapted to abut the piston 44 in case of a failure in the control pressure. The lever 74 is in the form of a U which is pivoted through both its legs at 78 and is slit transversely at 80 to receive an axis pin 82 which passes through the push-rod 84. When the rod 84 is pushed into the chamber 70 the lever 74 carries the pivot 86 of the member 76 forward so that its surfaces 94 and 96 are urged against the piston 44 and the spool 58. The spring 48 of the former is stronger than the spring 62 of the latter so that the spool moves into its cylinder 42, first covering the reservoir outlet 56 and then uncovering the accumulator outlet 52 from which pressure fluid then passes through channels 66 in the spool and over its reduced diameter end 68 into the chamber 70. The pressure in the chamber 70 then drives the piston 44 against its spring 48 to actuate the piston 20 of the master cylinder 12 through the push-rod 50. At the same time the pressure presses back on the push-rod 84 providing "feel" to the operator. Fig. 3 (not shown), illustrates another embodiment in which modifications are made to a number of the components to simplify manufacture and assembly.

Abstract: 725,317. Linkwork. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-OUEST. Feb. 20, 1953 [March 26, 1952], No. 4834/53. Class 80 (3) [Also in Group XXXIII] A control transmission system includes means interposed between the control member and the controlled member for normally imparting to it a cyclically variable force lower in amplitude than the resultant of passive resistance forces, e.g. friction, developed within the system. In the embodiment of Fig. 1, either a pilot's control column, or an automatic pilot, control through links 5a and 5b a servomotor 1 actuating a control surface 3. Links 5a and 5b are both joined to a lever 7 pivoted to the aircraft framework at 8, said lever having mounted on it an eccentric weight 12 driven by an electric motor 10 at a frequency which may be at least 200 c.p.s. The maximum force thus developed on the system is just insufficient to overcome friction and the like, and does not actually move the system, so that a slight force applied as a control in either direction will move the linkage each time the cyclic force approaches its maximum. A high frequency cyclic force gives the impression of continuous motion.

Filed: 1927-02-22
Abstract: 266,717. British Thomson-Houston Co., Ltd., (Assignees of Connell, A. C.). Feb. 23,1926, [Convention date]. Cut-out arrangements. - In an automaticallyreclosing circuit-breaker system, the circuitbreaker 3, between the supply line 1 and the load 2, is reclosed (after opening on fault) in accordance with the testing voltage across the load (which, when the circuit-breaker is open, is supplied with a testing current from the supply through a resistance 8 across the circuit-breaker) the reolosure being under the control of a twoelectrode valve 10 in which the electron stream is varied magnetically. As shown in the form in which a two-electrode, magnetically-controlled valve or " magnetron " is used, when the circuitbreaker 3 is tripped on overload the cathode 11 of the valve is supplied, through the back contacts 14 and the resistance 19, from the line 1. The plate 12 is supplied from the positive of the supply through the relay 15, and the field coil 13 is connected across the load. With heavy fault on the load, the voltage across it (transmitted through the resistance 8) is small and the output of the valve is a maximum; in consequence the relay 15 remains open. When the fault is cleared or reduced, the voltage across the load increases and the output of the valve falls off so that the relay 15 closes and, after a time interval imposed by the slow-acting relay 17, the circuit of the reclosing coil 7 is completed. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of an ordinary three-electrode valve in lieu of the "magnetron" with the grid taking the place of the field coil. This subject-matter does not appear in the Specification as accepted.
